【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical cross-sectional view showing the internal structure of the dishwasher of the present invention, and FIG. 2 is a perspective view of an upper rinsing nozzle. A cleaning chamber 3 which is opened / closed by 2 is formed as a compartment, and an upper cleaning nozzle 4 having a plurality of cleaning nozzle ports 4A for jetting cleaning water downward is rotatably arranged on the upper part of the cleaning chamber 3. An upper rinse nozzle 5 that rotates concentrically with the upper cleaning nozzle 4 is disposed slightly below the upper cleaning nozzle 4. The upper rinse nozzle 5 has a plurality of rinse nozzle ports 5A for jetting rinse water downward and a plurality of auxiliary rinse nozzle ports 5B for jetting rinse water upward.

A lower cleaning nozzle 6 having a plurality of cleaning nozzle openings 6 A for spraying cleaning water upward is rotatably arranged at the lower part of the cleaning chamber 3, and the rinse is slightly above the lower cleaning nozzle 6. A lower rinse nozzle 7 having a plurality of rinse nozzle openings 7A for jetting water upward is rotatably arranged concentrically with the lower cleaning nozzle 6. Further, between the upper cleaning nozzle 4 and the upper rinsing nozzle 5, and the lower cleaning nozzle 6 and the lower rinsing nozzle 7, a rack 9 accommodating an object 8 to be cleaned is mounted on a support rail 10.

Further, a cleaning tank 12 whose upper surface is covered with a removable filter 11 is defined in the lower part of the main body below the cleaning chamber 3, and an overflow pipe 13 is erected in the cleaning tank 12 and the cleaning tank 12 is installed. The water level of 12 is defined as a predetermined water level. On the other hand, between the upper and lower cleaning nozzles 4 and 6 and the cleaning tank 12, a cleaning pump for circulating the cleaning water of about 60 ° C mixed with the detergent stored in the cleaning tank 12 to the upper and lower cleaning nozzles 4 and 6. Between the upper and lower rinse nozzles 5, 7 and the booster 15 arranged in parallel with the main body 1, the rinse water of about 80 ° C. stored in the booster 15 is fed to the upper and lower rinse nozzles 5, 7. A rinsing pump 16 is provided for this purpose.

In the above configuration, first, the object to be cleaned 8 is housed in the rack 9 and cleaned, and is installed on the support rail 10 of the cleaning chamber 3 to start the cleaning operation. In the cleaning operation, the cleaning water stored in the cleaning tank 12 is circulated to the upper cleaning nozzle 4 and the lower cleaning nozzle 6 by the operation of the cleaning pump 14, and the nozzles 4 and 6 rotate to clean the cleaning water. The cleaning object is cleaned by spraying downward from the cleaning nozzle port 4A of the nozzle 4 and upward from the cleaning nozzle port 6A of the lower cleaning nozzle 6. The sprayed cleaning water drops through the filter 11 into the cleaning tank 12 and is circulated again to the upper and lower cleaning nozzles 4 and 6.

When the cleaning operation is performed for a predetermined time, the cleaning pump 14 stops, the cleaning operation ends, and the rinsing operation subsequently starts. In the rinsing operation, the rinsing pump 16 operates to feed the rinsing water of the booster 15 to the upper rinsing nozzle 5 and the lower rinsing nozzle 7, and both nozzles 5 and 7 rotate the rinsing water to the rinsing nozzle of the rinsing nozzle 5. The nozzle 8A sprays downward and the rinse nozzle 7 of the lower rinse nozzle 7 sprays upward to spray the object 8 to be cleaned. At this time, rinsing water is sprayed upward from the auxiliary rinsing nozzle port 5B of the upper rinsing nozzle 5, and this upward rinsing water flushes away the rinsing water that adheres to the top plate 3A of the rinsing chamber 3 in the rinsing operation. At the position where 5 overlaps with the upper cleaning nozzle 4, the cleaning water attached to the upper cleaning nozzle 4 is washed away.

Therefore, when the rinsing operation is completed, it is possible to prevent the cleaning water from dripping from the top plate 3 A of the cleaning chamber 3 and the upper cleaning nozzle 4 onto the object to be cleaned 8.
